Coordinate point A (Ax, Ay) and 303 coordinate point B (Bx,
When performing cutting and pasting editing of (within the range of a rectangular frame consisting of By), the unit of cutting and pasting is one rectangular frame, and the lengths of the rectangular frame's size X and Y can be freely specified. Figure 30
4, when cutting out a figure surrounded by a curved line, place the mouse cursor 311 at the coordinate point A305. The figure 305 is set as the base point of the cutting frame, and by moving the mouse cursor, a rectangular frame for specifying the cutting range is drawn. Mouse cursor from 3-5 to 306
, 307, 308°, 309.310. Rectangular frames are also 312 to 313, 314, 315, 316
As you move the mouse cursor, the image will be enlarged sequentially. Finally, in a frame 316 in which the graphic range of the cut portion 304 is contained within the rectangular frame, a cut rectangular frame is set at the positions of the coordinate point A305 and the coordinate point B510 of the cut rectangular frame. After setting the cutting range with a 317 rectangular frame, display a 319 rectangular frame of the same size as the cutting frame in a different position on the screen to set the next position to paste the rectangular frame containing the cut shape, and then paste it. specifies the position. When pasting a cutting frame, the image original is moved to another position 319, 320 and pasted after specifying the same magnification or enlargement/reduction of the transfer figure in the frame.

[Problem to be solved by the invention]

In conventional graphic editing devices, cutting and pasting of parts can only be done in units of one rectangular frame, that is, in units of dots or dot boundaries. For example, the procedure for cutting out a part of a shape that has been inserted and pasting the cut shape with the shape that has been inserted on a separate sheet is to divide the shape into multiple small rectangular frames, cut them out, assemble them, and paste them dot by dot. It was necessary for the operator to be aware of the fact that the figures do not shift. As a practical matter, it has been impossible to compose and paste figures divided into a plurality of pieces while making the operator aware of the number of dots on the graphic display screen.

Since it was not possible to delete parts of a shape that was inserted in one go, it was necessary to set a small rectangular frame and divide it several times to delete parts, which took a lot of time and effort. In Figure 4, if you set the cutting range for the figure 402 in the figure using the rectangular frame 403, the unnecessary figure ranges 404, 405, 406, and 407 will be included in the cutting frame, and 402 will be pasted on the separate blank document in 408. case is 410,411,412
Even the unnecessary graphic part of ゜413 is pasted.

Next, in Fig. 414, the figure 416 in the figure is replaced with 415
If you set the cutting range with a rectangular frame and move the 422 figure on the 421 attachment near the 424 sketch and paste it together, the 424 sketch and 423 paste will have an overlapped area with the rectangular frame, and the 425 sketch will be pasted 423. It disappeared afterwards.

Also, if you try to delete the 428 figure part at 426 in the figure, the setting range of the 427 rectangular frame at - times is 429
, 430, 431, and 432 are deleted within the rectangular area 433 and 434 in the figure.
